Summary:An inverter of a driving motor of a vehicle comprises a first path, a second path, a first switching unit, a first output path, a second output path, a second switching unit, and a control unit. The DC power of the inside of the driving motor is connected to a ground through the first path via a first resistance and a NTC thermistor which resistance becomes changed according to the inner temperature of the driving motor. The DC power is connected to the ground through the second path via the first resistance, the NTC thermistor, and a second resistance. The first switching unit selects one of the first and second paths. The first output path connects a voltage applied from a joint between the first resistance and the NTC thermistor to the outside. The second output path connects a voltage applied from a joint between the NTC thermistor and the second resistance to the outside. Temperature values inside the driving motor are calculated by the control unit. By using the inverter, temperature of the driving moto
